The Froggattimyia-Anagonia genus group (Diptera: Tachinidae)
Abstract
The genera here reviewed have in common many morphological attributes, and in both, all species are parasites of the larvae of leaf-eating insects—pergid sawflies for Froggattimyia and chrysomelid or curculionid beetles for Anagonia. Perhaps significantly, the host larvae themselves show a degree of physical resemblance and all are charged strongly with eucalyptus oil from their foodstuffs. Twelve species are recognized in Froggattimyia, the following six are new: F. carnei, F. coracina, F. macdonaldi, F. woodorum, F. truncata, and F. vicina, one is near F. hirta and remains undescribed. Twenty-five species are recognized in Anagonia, the following sixteen are new: A. angustifrons, A. commoni, A. conformis, A. crosskeyi, A. dayi, A. errator, A. latistylus, A. loripes, A. minor, A. norrisi, A. perplexa, A. propinqua, A. similis, A. teratostylus, A. uptoni, and A. zentae; F. tillyardi Malloch is newly combined in Anagonia. Most species are so highly variable as to make a classification based on internal structure at best tentative.
